SPRING-WHEEL.

Specification of Letters Patent.

Patented April 16, 1907.

Application filed November 24, 1906. Serial No. 344,970.

To aZL Wh/O'I'H/ it may concern.-

Be it known that I, JACOB D. SOWER, a citizen of the United States, residing at'Elmo, in the county of Dickinson and State of Kan- .sas, have invented certain new and useful Improvements in Spring-Wheels, of which the following is a specification.

This invention has for its object to provide a novel form of tire for vehicle-wheels, such as automobiles and mechanica-lly-propelled carriages, said tire embodying all the advantages of a pneumatic or cushion tire, but free from the disadvantages of being readily punctured or injured, so as to cause deflation in tires of the pneumatic type or permanent injury to tires of the cushion variety when passing over a sharp obstacle, such as stone or glass. j i

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of a the means for effectingthe result reference is to be had to the following description and accompanying' drawings.

While theinvention may beadapted to different forms and conditions by changes in the structure and minor details without departing from the spirit or essential features thereof, still the preferred embodiment is shown in the accompanying drawings, in which Figure 1 is a side view of a vehicle-wheel provided with a tire embodying the invention. Fig. 2 is a plan view of a portion of the tire as seen looking from the tread side. 3 is a cross-section of the tire onthe line a: as of Fig. 2. Fig. 4 is a plan view, of a portion of the-blank from which the rim of the tire is formed.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The tire comprises a rim 1 and a springcoil 2, the latter constituting the tread, whereas the rim is channeled and forms a seat for said coil,the latter being secured within the.

are scalloped at their edges to providedepressions' and "elevations in alternation.

and is approximately of U form in trans-' While the rim may be constructed of any material, it is preferred to form the same of sheet metal, having its opposite longitudinal edges formed'with indentations and the strip being curved uponitself between its longitu dinal edges to form the channel or seat 'in' which the spring-coil 2 is fitted. The rim 1' is adapted to be secured to the rim of the vehicle-wheel in any convenient and substantial way.

The spring-coil 2 may be continuous or formed of sections connected in any manner so as to form an effect of continuous coil or yielding tread.

The spring-coil is formed of spring-wire of suitable gage according to the load to be sustaincd by the tire. The spring-coil is fitted within the channel of the rim 1 and is held in' place by fastenings 3 and transverse rods or bars 4, the latter being passed through openingsin the elevated portions of the side members of the rim. The-transverse rods or bars 4 may be headed at one end and threaded for a short distance at the opposite end to receive nuts, by means of which they are secured to the rim when placed. in position. Thefastenings 3 consist of hook-bolts which are passed through openings near the upper edges of the side portions of the rim, the hooks of said bolts engaging with elements of the spring-coil, thereby preventing transverse displacement of said spring-coil when subjected to lateral stress, as when the vehicle is making a short curve. The transverse rods or bars 4 engage with elements of the spring-coil and subdivide the latter into sections, thereby preventing circumferential movement of the coil upon the rim or gripping the said coil upon the rim. The outer portion of the'springcoil projects some distance beyond the edges of the side bars of the rim 1 to sustain the load and prevent the edges of the rim from coming in contact with the surface upon which the vehicle may be traveling.
